Abstract : A computational fluid dynamics study of the exit jet of the U.S. Army Research Laboratory's 1.68-m diameter shock tube is presented. The shock tube exit jet provides a test environment in which to assess vehicle response to non-ideal blast. In the present study, time-accurate Navier-Stokes solutions are generated to simulate a shock tube exit jet test in which pressure probe measurements were obtained. The computational results are compared to the experimental data, as well as to analytical results and other empirical data. An examination is made of the jet flow field structure, and the computational accuracy and requirements are assessed.
